• General Symposia

Symposium 1 (Tue, September 12, AM)

"Time and space connected by colloid and interface chemistry"

The spread of coronavirus infections has severed time and space, drastically changing lifestyles and the world of chemistry. Even under these circumstances, colloid and interface chemistry has continued to develop in various fields, transcending time and space. This symposium will provide an opportunity to share new approaches that transcend time and space in the 29-year history of emulsifier-free emulsions.
 

 

Symposium 2 (Tue, September 12, PM)

"Challenges for Next-Generation Materials: Material Design and Process Optimization Using Modern Colloid Technology"

In this program, we have invited a wide range of experts to share their latest research results and solve technical issues on the role of colloid chemistry in materials design and creation, as well as process design. In particular, the basic technologies that support cutting-edge research in data-driven material design, particulate material design, and dispersion control, as well as the new properties and possibilities of materials created by their application, will be introduced. The purpose of this event is for participants to gain new knowledge and exchange information with each other for future research and industrial applications.

 

Symposium 3 (Wed, September 13, AM)

"New Horizon of Surface Chemistry for Fluorinated Materials"

Organo-fluorine materials are known as a group of materials that contribute greatly to the realization of a smart society, as they exhibit many unique interfacial properties not found in non-fluorine hydrocarbons, such as water and oil repellency, heat resistance, and low friction. On the other hand, there is no theoretical framework that can systematically explain these properties at the molecular level, and research and development is conducted in a haphazard and inefficient manner. In recent years, the hierarchical dipole array theory (SDA theory) has been proposed to explain these properties scientifically, and a fundamental review of this situation is underway. In this symposium, we will review and discuss new developments in interfacial chemistry based on this theoretical framework.

 


Symposium 4 (Thu, September 14, AM)

"Interfacial nanophotonics -Dynamics of light-matter interaction at the liquid-solid interface-"

Novel optical materials that utilize (collect) nanostructures, as typified by metamaterials, are not simply a scale law associated with the miniaturization of structures. The novel optical materials using (collected) nanostructures, such as metamaterials, are not simply a scale rule associated with the miniaturization of the structure, but are also a result of the special optical properties expressed at the surface/interface of various nanomaterials such as metal nanostructures and nanocarbon materials. The special optical properties that develop at the surface/interface of various nanomaterials, such as metal nanostructures and nanocarbon materials, are completely different from those of the bulk materials. The principle is based on the interaction of light at the nanosurface/interface, which is completely different from that of the bulk material. The special optical properties at the nanosurface/interface are quite different from those of the bulk materials. In this symposium, we would like to introduce the method of creating optical materials using the physical properties peculiar to such surfaces/interfaces. This symposium will review the methods of optical material creation using the physical properties peculiar to such surfaces/interfaces, microscopic techniques using the optical properties peculiar to surfaces/interfaces, and molecular analysis techniques, etc., in a broad and cross-disciplinary manner. We will give a broad and cross-disciplinary overview. In particular, the latest science and engineering created by the interaction between nanostructures and light at the solid/liquid interface will be discussed. We will discuss about the latest science and engineering of the interaction between nanostructures and light at the solid/liquid interface, and the future development of surface/interface x photonics research. We would like to discuss the future development of surface/interface x photonics research.

 

Symposium 5 (Thu, September 14, PM)

"In situ analyses on nanostructural change in aqueous dispersions"

Tracking structural changes caused by adsorption and reactions (in-situ analyses) are attracting attention. In this symposium, we will focus on nanostructures related to interfaces in water, and various assemblies (surfactants, nanoparticles, nanosheets, etc.) using synchrotron X-ray diffraction, small-angle X-ray scattering, and small-angle neutron scattering techniques to discuss structural changes.
